Fulltext The pattern of acute renal failure in Kelantan

Zainal D, Loo CS

Singapore Med J, 1996 Feb;37(1):44-7.
PMID: 8783912

Acute renal failure (ARF) has undergone many changes with advances both in diagnosis and therapy. A retrospective study covering three and a half years from June 1986 to December 1989 of adults admitted to Hospital of the University of Science Malaysia examined the various aspects of presentation of the syndrome, management and areas where improvement can be made. A total of 164 patients were included in the study. 61.6% were male and 38.4% were female. The mean age was 49.8 +/- 17.2 years with 70% of patients being more than 40 years old. The aetiologies of acute renal failure were analysed and discussed. The majority of the patients (80%) had non-oliguric acute renal failure. Oliguric acute renal failure patients have higher mortality and more frequently need dialysis. Early recognition of acute renal failure and discerning use of nephrotoxic drugs could result in decrease in incidence and severity of renal failure.

Fulltext The status of intermittent peritoneal dialysis in Hospital University Science Malaysia

Zainal D, Loo CS

Singapore Med J, 1995 Aug;36(4):379-82.
PMID: 8919150

Acute (stab) peritoneal dialysis is commonly practised in Malaysia. This study is designed to improve the management of peritoneal dialysis (PD) in Hospital University Science Malaysia (HUSM). Consecutive peritoneal dialysis (PD) on adult inpatients from May 1992 to September 1992 were reviewed prospectively. There were 40 episodes of peritoneal dialysis on 27 patients during this period given at the rate of 2 PD per week. The mean age of patients were 53 +/- 15 years. Uraemia was the main indication for dialysis, while hyperkalaemia and pulmonary oedema were indications for urgent dialysis. Complications occurred in 14 episodes of dialysis (35%). The most common complication was bleeding in the peritoneal cavity while peritonitis was the second most common complication. Dialysis episodes complicated by peritonitis were done by less experienced performers compared to uncomplicated dialysis episodes. Overall mean time spent on each dialysis and time per cycle were longer than recommended (59 +/- 24 hours and 77 +/- 14 minutes). In conclusion, acute PD performed on patients admitted in Hospital University Malaysia was safe and had complication rates comparable to other established centres. However, improvements are possible through closer supervision of new doctors and tighter nursing precautions.

Fulltext Screening for bacteriuria in Malaysian school children

Zainal D, Baba A

Singapore Med J, 1994 Aug;35(4):374-5.
PMID: 7899895

Urinary tract infection is the most common of bacterial infections. Screening children for asymptomatic bacteriuria to prevent pyelonephritis and renal scarring is widely recommended. In Malaysia no such attempt has been made to establish the prevalence of asymptomatic bacteriuria. Bacteriuria was screened among 44,816 healthy school children from three different districts in Kelantan. There were 23,132 boys and 21,684 girls. The prevalence of bacteriuria was 0.12% after second screening. Higher prevalence was seen in other reports.

Oral recurrent aphthous ulcers/stomatitis: prevalence in Malaysia and an epidemiological update

Zain RB

J Oral Sci, 2000 Mar;42(1):15-9.
PMID: 10808270

One of the objectives of this short communication was to add to the literature on the prevalence of oral recurrent aphthous stomatitis (ORAS). This research is based on a total of 11,697 randomly selected Malaysian subjects with an age range of 25-115 years and a mean age of 44.5 +/- 13.9 years who were examined for oral mucosal lesions (ORAS). The prevalence of ORAS detected during the oral examination (average point prevalence) was found to be 0.5% (64 subjects). ORAS formed 5.7% of all lesions detected during the survey. The average point prevalence of ORAS was highest in the indigenous people of Sabah and Sarawak (1.2%), followed by the Chinese (0.7%), the Malays (0.5%) and the Indians (0.1%). This difference was statistically significant (p < 0.001). A review of the English literature on the prevalence of ORAS revealed different prevalence types used by different researchers, namely average point prevalence (APP), self reported life-time prevalence (SLP) and self reported two-year prevalence (STP). The other objective of this paper was to present the different types of prevalence that have been reported in the literature and to discuss the usefulness of such prevalence types in relation to using epidemiology in deriving certain possible etiological associations.

Zain RB, Khoo SP, Yeo JF

Singapore Dent J, 1995 Jul;20(1):8-10.
PMID: 9582682

A clinical analysis of 304 cases of pyogenic granuloma (excluding pregnancy tumour) were obtained from the clinical evaluations submitted by clinicians while sending specimens for biopsy. The average age of the patients with pyogenic granuloma was 28.9 years with a peak age incidence in the second decade. More female patients were affected and the lesions present mainly in the Chinese. The majority of the lesions were ulcerated and pedunculated. The lesions had a mean diameter of 10.8 mm with a mean lesion duration of 6.0 months. The gingiva was the prevalent site for these lesions with a greater number being located in the maxilla. The recurrence rate was found to be 14.1%.

Zain RB, Ikeda N, Razak IA, Axéll T, Majid ZA, Gupta PC, et al.

Community Dent Oral Epidemiol, 1997 Oct;25(5):377-83.
PMID: 9355776

The prevalence of oral mucosal lesions in Malaysia was determined by examining a representative sample of 11,707 subjects aged 25 years and above throughout the 14 states over a period of 5 months during 1993/1994. A two-stage stratified random sampling was undertaken. A predetermined number of enumeration blocks, the smallest population unit in the census publication, was selected from each state. With the selected enumeration block, a systematic sample of living quarters was chosen with a random start. The survey instrument included a questionnaire on sociodemographic characteristics and a clinical examination. The clinical examination was carried out by 16 specially trained dental public health officers and the diagnosis calibrated with a final concordance rate of 92%. The age in the sample ranged from 25 to 115 years with a mean of 44.5+/-14.0. The sample comprised 40.2% males and 59.8% females; 55.8% were Malays, 29.4% Chinese, 10.0% Indians and 1.2% other ethnic groups. Oral mucosal lesions were detected in 1131 (9.7%) subjects, 5 (0.04%) had oral cancer, 165 (1.4%) had lesions or conditions that may be precancerous (leukoplakia, erythroplakia, submucous fibrosis and lichen planus) and 187 (1.6%) had betel chewer's mucosa. The prevalence of oral precancer was highest amongst Indians (4.0%) and other Bumiputras (the indigenous people of Sabah and Sarawak) (2.5%) while the lowest prevalence was amongst the Chinese (0.5%).

Zain NM, Low WY, Othman S

Southeast Asian J. Trop. Med. Public Health, 2015 May;46(3):526-38.
PMID: 26521527

Pregnancy among unmarried women may have negative social and health implications in Malaysia. The number of pregnancies among unmarried women has increased in Malaysia, but the socio-demographic profile of these women is unclear. This study aims to evaluate the characteristics of unmarried pregnant women and the factors associated with unmarried pregnancies among young women in Malaysia. We conducted a cross sectional study at six hospitals and six women's shelters in Peninsular Malaysia during 2011-2012. Unmarried pregnant women were compared with married pregnant women. Participants were interviewed using a structured questionnaire asking for socio-demographic data, family background, risky sexual behavior, social support and pregnancy details. A total of 484 women (239 unmarried and 245 married) were included in the study. Most unmarried subjects were adolescents, from urban areas, from a low socioeconomic group, and lived with parents prior to pregnancy. Age (OR=0.67; 95% CI: 0.61-0.74), studying status (OR=17.33; 95% CI: 2.65-113.19), alcohol use (OR=40.46; 95% CI: 2.51-652.38) exposure to pornographic material (OR=13.48; 95% CI: 3.24-56.01), contraceptive use (OR=0.20; 95% CI: 0.08-0.51), and social support (OR=0.90; 95% CI: 0.86-0.94) were all associated with unmarried pregnancy. These factors need to be considered when.designing an intervention program.

Fulltext Profile of in-patient suicides in two hospitals in Malaysia

Zain AM

Med J Malaysia, 1991 Jun;46(2):171-6.
PMID: 1839422

A study of completed in-patient suicides at the University Hospital Kuala Lumpur (UHKL) and Hospital Bahagia Ulu Kinta (HBUK) between 1st January 1967 to 31st December 1987 were conducted. Records of completed in-patient suicides during the period were exhaustively studied. Only 18 cases were from UHKL and 23 cases were from HBUK. It was found that the suicide patients were mainly young Chinese males from the lower socio economic group. The main reasons for suicide were interpersonal conflicts and physical illness. Alcohol was not an important factor unlike patients in the West.. Suicidal intent was also important. Many of the suicides were committed during the early hours of the morning and they usually occurred at inaccessible places. The method was strongly influenced by availability. To the best knowledge of the author, this is the first study of in-patient suicides in Malaysia.

Zailinawati AH, Ariff KM, Nurjahan MI, Teng CL

Asia Pac J Public Health, 2008;20(3):224-33.
PMID: 19124316 DOI: 10.1177/1010539508316975

This study aimed to determine the prevalence and pattern of insomnia in a Malaysian population aged 30 to 70 years. The sample consisted of 1611 subjects, recruited by stratified random sampling and interviewed using a semistructured questionnaire conducted in 2004. This was a community-based survey in 4 Malaysian states. The prevalence of insomnia symptom was 33.8%, and 12.2% of the subjects had chronic insomnia. Insomnia was more common among elderly; those who were separated, divorced, or widowed; and those who smoked at bedtime. Subjects with insomnia had a higher prevalence of feeling depressed (12.7), loss of concentration (19.1%), exhaustion (17.2%), poor memory (9.2%), decreased work productivity (6.4%), and perceived poor health status (40.9%; all, P < .05). A total of 22.2% of those with insomnia had excessive daytime sleepiness based on their Epworth Sleepiness Score (P =

Fulltext Pain morbidity in primary care - preliminary observations from two different primary care settings

Zailinawati AH, Teng CL, Kamil MA, Achike FI, Koh CN

Med J Malaysia, 2006 Jun;61(2):162-7.
PMID: 16898306 MyJurnal

The prevalence of pain complaints as a reason for patient-doctor encounters in the local primary care setting is unknown. We performed a cross-sectional survey of such encounters in one public primary care clinic (KK) and 17 general practice clinics (GP), from the city of Seremban, Negeri Sembilan, Malaysia. Reasons for visits were recorded by doctors in KK and medical students in GP using a structured questionnaire. Morbidity data was coded using the International Classification of Primary Care (ICPC-2). A total of 2234 encounters were recorded (80.9% from KK, 19.1% from GP). The overall prevalence of pain complaints was 31.9% with a significant difference between the two cohorts (KK 28.7% and GP 45.2%, p<0.001). Musculoskeletal pain complaints were more common in KK than GP (40.9% versus 29.7%, p<0.05). Of the 3 main ethnic groups in Malaysia (Malay, Chinese and Indian) the Indian patients at KK had the highest prevalence of pain complaints and the Chinese at the GP had the lowest. Thus pain was a common complaint in the two different primary care settings studied. Some of the differences observed are probably due to the differences in the healthcare seeking behaviour of patients consulting at these two settings as well as differences in the payment systems.

Zahary MN, Harun NS, Yahaya R, Nik Him NAS, Rohin MAK, Ridzwan NH, et al.

Diabetes Metab Syndr, 2019 04 25;13(3):2015-2019.
PMID: 31235129 DOI: 10.1016/j.dsx.2019.04.048

BACKGROUND AND OBJECTIVES: Metabolic syndrome (MetS) is characterized as a cluster of metabolic disorder including increased blood pressure, elevated blood glucose level, high cholesterol level and visceral fat obesity. Polypeptide hormones such as adiponectin and resistin play a significant role in glucose and lipids metabolism, liver and pancreas function. This study aimed to investigate the relationship between serum adiponectin and resistin with MetS criteria among Temiar subtribe in Kuala Betis.
MATERIALS AND METHODS: This cross sectional study involved 123 subjects from Temiar subtribe in Kuala Betis, Gua Musang, Kelantan. MetS criteria were measured according to standard protocol by modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guideline. Anthropometric and biochemical measurements were performed including serum adiponectin and resistin for every study subjects.
RESULTS: Serum adiponectin was significantly lower in MetS subjects (7.98 ± 5.65 ng/ml) but serum resistin was found to be significantly higher in MetS subjects (11.22 ± 6.34 ng/ml) compared to non-MetS subjects with p

Relationship Between ABCB1 Polymorphisms and Cold Pain Sensitivity Among Healthy Opioid-naive Malay Males

Zahari Z, Lee CS, Ibrahim MA, Musa N, Mohd Yasin MA, Lee YY, et al.

Pain Pract, 2017 09;17(7):930-940.
PMID: 27996183 DOI: 10.1111/papr.12546

BACKGROUND: Endogenous and exogenous opioids are substrates of the permeability glycoprotein (P-gp) efflux transporter, which is encoded by the ABCB1 (MDR1) gene. Genetic polymorphisms of ABCB1 may contribute to interindividual differences in pain modulation and analgesic responses. We investigated the relationship between ABCB1 polymorphisms and cold pain sensitivity among healthy males.
METHODS: Cold pain responses, including pain threshold and pain tolerance, were measured using the cold-pressor test (CPT). DNA was extracted from whole blood and genotyped for ABCB1 polymorphisms, including c.1236C>T (rs1128503), c.2677G>T/A (rs2032582), and c.3435C>T (rs1045642), using the allelic discrimination real-time polymerase chain reaction.
RESULTS: A total of 152 participants were recruited in this observational study. Frequencies of mutated allele for c.1236C>T, c.2677G>T/A, and c.3435C>T polymorphisms were 56.6%, 49.7%, and 43.4%, respectively. Our results revealed an association of the CGC/CGC diplotype (c.1236C>T, c.2677G>T/A, and c.3435C>T) with cold pain sensitivity. Participants with the CGC/CGC diplotype had 90% and 72% higher cold pain thresholds (87.62 seconds vs. 46.19 seconds, P = 0.010) and cold pain tolerances (97.24 seconds vs. 56.54 seconds, P = 0.021), respectively, when compared with those without the diplotype.
CONCLUSION: The CGC/CGC diplotype of ABCB1 polymorphisms was associated with variability in cold pain threshold and pain tolerance in healthy males.

Eur J Pediatr, 2019 Aug;178(8):1267-1274.
PMID: 31222391 DOI: 10.1007/s00431-019-03403-x

Limited data are available on the survival of patients with Down syndrome and congenital heart disease (CHD) from middle-income countries. This retrospective cohort study was performed to determine the trends in the prevalence and survival of such patients born from January 2006 to December 2015 in Malaysia. Among 754 patients with Down syndrome, 414 (55%) had CHD, and no significant trend was observed during the 10 years. Of these 414 patients, 30% had lesions that closed spontaneously, 35% underwent surgery/intervention, 9% died before surgery/intervention, and 10% were treated with comfort care. The overall mortality rate was 23%, the median age at death was 7.6 months, and no significant changes occurred over time. The early and late post-surgery/intervention mortality rates were 0.7% and 9.0%, respectively. Most deaths were of non-cardiac causes. The overall 1-, 5-, and 10-year survival rates were 85.5%, 74.6%, and 72.9%, respectively. Patients with severe lesions, persistent pulmonary hypertension of the newborn, atrioventricular septal defect, and pulmonary hypertension had low survival at 1 year of age.Conclusion: The prevalence of CHD in patients with Down syndrome is similar between Malaysia and high-income countries. The lower survival rate is attributed to limited expertise and resources which limit timely surgery. What is Known: • The survival of patients with Down syndrome with congenital heart disease (CHD) has improved in high-income countries. However, little is known about the survival of patients with Down syndrome with CHD from middle-income countries. • In the Caucasian population, atrioventricular septal defect is the most common type of CHD associated with Down syndrome. What is New: • In middle-income countries, the prevalence of CHD is the same as in high-income countries, but with a lower survival rate. • In the Asian population, ventricular septal defect is the most common type of CHD in patients with Down syndrome.

Profile of solvent abusers (glue sniffers) in East Malaysia

Zabedah MY, Razak M, Zakiah I, Zuraidah AB

Malays J Pathol, 2001 Dec;23(2):105-9.
PMID: 12166590

Solvent abuse is deliberate sniffing of an organic solvent for the intention of altering the physiological state of the individual. It is also commonly known as glue sniffing because glue is the most commonly abused substance. This form of substance abuse is widespread throughout the world and usually popular among secondary school children and young adults because of its easy availability and it is cheaper compared with most drugs of abuse. In Malaysia this problem has been recognized especially among the children in East Malaysia. In this study, 37 children and young adults from or around Kota Kinabalu, Sabah were referred to Bukit Padang Psychiatric Hospital by the Anti-drug Task force for suspected solvent abuse. These children were interviewed using questionaire and examined physically. Blood and urine were analysed for toluene and hippuric acid. 27 of the children, age ranging between 8 and 20 years, willingly admitted to sniffing glue for a period between a few months to 2 years. Most of them were children of Fillipino illegal immigrants in Kota Kinabalu. Biochemical parameters were found to be normal. Two of them were pale with low hemoglobin and 7 had eosinophilia. Haematuria and proteinuria were found in 21 children (78%). 16 blood samples with toluene levels ranging from 0.3 to 41 microg/ml and 10 urine samples have elevated urinary hippuric acid levels ranging from 1.2 to 7.4 mg/ml. Strong positive correlation was noted between mean blood toluene levels and duration of abuse.

Breastfeeding and postnatal depression: a prospective cohort study in Sabah, Malaysia

Yusuff AS, Tang L, Binns CW, Lee AH

J Hum Lact, 2016 May;32(2):277-81.
PMID: 26644418 DOI: 10.1177/0890334415620788

BACKGROUND: Postnatal depression is a disorder that can lead to serious consequences for both the mother and infant. Despite the extensively documented health benefits of breastfeeding, its association with postnatal depression remains uncertain.
OBJECTIVE: To investigate the relationship between full breastfeeding at 3 months postpartum and postnatal depressive symptoms among mothers in Sabah, Malaysia.
METHODS: A prospective cohort study of 2072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36 to 38 weeks of gestation and followed up at 1 and 3 months postpartum. Depressive symptoms were assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale (EPDS). Repeated-measures analyses of variance was performed to compare the depression scores over time and between subgroups of breastfeeding mothers.
RESULTS: Approximately 46% of women were fully breastfeeding their infants at 3 months postpartum. These mothers had significantly (P < .001) lower mean EPDS scores at both 1 and 3 months postpartum (mean ± SD, 4.14 ± 4.12 and 4.27 ± 4.12, respectively) than others who did not initiate or maintain full breastfeeding for 3 months (4.94 ± 4.34 and 5.25 ± 4.05, respectively). After controlling for the effects of covariates, the differences in EPDS scores remained statistically significant (P = .001) between the 2 breastfeeding groups.
CONCLUSION: Full breastfeeding appeared to be negatively associated with postnatal depressive symptoms for mothers residing in Sabah.
Study site: 5 maternal and child health clinics in Kota Kinabalu and Penampang Districts of Sabah, Malaysia

Molecular heterogeneity of glucose-6-phosphate dehydrogenase deficiency in Malays in Malaysia

Yusoff NM, Shirakawa T, Nishiyama K, Ghazali S, Ee CK, Orita A, et al.

Int J Hematol, 2002 Aug;76(2):149-52.
PMID: 12215013 DOI: 10.1007/BF02982577

Multiplex polymerase chain reaction (PCR) using multiple tandem forward primers and a common reverse primer (MPTP) was recently established as a comprehensive screening method for mutations in X-linked recessive diseases. In the work reported here, MPTP was used to scan for mutations of the glucose-6-phosphate dehydrogenase (G6PD) gene. Mutations in exons 3,4,5,6,7,9, 11, and 12 of the G6PD gene were screened by MPTP in 93 unrelated Malaysian patients with G6PD deficiency. Of the 93 patients, 80 (86%) had identified mutations. Although all of these were missense mutations, identified nucleotide changes were heterogeneous, with 9 mutations involving various parts of the exons. These 9 mutations were G-to-A nucleotide changes at nucleotide 871 of the G6PD gene (G871A), corresponding to G6PD Viangchan, G6PD Mediterranean (C563T), G6PD Vanua Lava (T383C), G6PD Coimbra (C592T), G6PD Kaiping (G1388A), G6PD Orissa (C131G), G6PD Mahidol (G487A), G6PD Canton (G1376T), and G6PD Chatham (G1003A). Our results document heterogeneous mutations of the G6PD gene in the Malaysian population.
